Spanish satellite operator Sateliot has launched its first research and development project with the European Space Agency (ESA) to test a new satellite IoT system that operates independently of traditional navigation systems such as GPS. The initiative, called FreeGNSSNetwork, aims to improve the resilience of IoT networks against signal interference while reducing costs and power consumption for connected devices.
The project, developed in collaboration with technology firm GMV, uses advanced algorithms that allow IoT devices to determine their position directly from satellite signals. This breakthrough would maintain precise and stable communications even in “GNSS-denied” environments, such as conflict zones or areas where satellite navigation systems are disrupted. Laboratory testing is already underway, with in-orbit demonstrations planned using prototype satellites and terminals to deliver Positioning, Navigation and Timing (PNT) data directly to IoT devices.
“This project positions Spain as a benchmark in satellite innovation and connects European industry to new IoT and 5G service markets,” said Jaume Sanpera, Sateliot’s co-founder and CEO, in a statement. “It is a dual-use technology that enhances autonomy, resilience, and energy efficiency across both civil and defense applications.”
Sateliot’s LEO satellite constellation is the first based on the 5G standard, allowing commercial NB-IoT devices to connect directly from space and extending affordable connectivity to remote areas, the company said.
